teuthology-lock and choosing a kernel

Hi Andrew,

After successfully locking a centos 6.5 VPS in the community lab with

teuthology-lock --lock-many 1 --owner loic@dachary.org --machine-type vps --os-type centos --os-version 6.5

it turns out that it has a 2.6.32 kernel by default. A more recent kernel is required to run the ceph-disk tests because it relies on /dev/loop handling partition tables as a regular disk would. After installing a 3.10 kernel from http://elrepo.org/tiki/kernel-lt and rebooting, it was no longer possible to reach the machine.

The teuthology-suite command has a -k option which suggest there is a way to specify the kernel when provisioning a machine. The command

./virtualenv/bin/teuthology-suite --dry-run -k testing --priority 101 --suite rgw --suite-branch firefly --machine-type plana,burnupi,mira --distro ubuntu --email loic@dachary.org --owner loic@dachary.org  --ceph firefly-backports

shows lines like:

2015-03-08 13:43:26,432.432 INFO:teuthology.suite:dry-run: ./virtualenv/bin/teuthology-schedule --name loic-2015-03-08_13:43:06-rgw-firefly-backports-testing-basic-multi --num 1 --worker multi --priority 101 --owner loic@dachary.org --description 'rgw/multifs/{clusters/fixed-2.yaml fs/btrfs.yaml rgw_pool_type/erasure-coded.yaml tasks/rgw_multipart_upload.yaml}' -- /tmp/schedule_suite_AQ2b6w /home/loic/src/ceph-qa-suite_firefly/suites/rgw/multifs/clusters/fixed-2.yaml /home/loic/src/ceph-qa-suite_firefly/suites/rgw/multifs/fs/btrfs.yaml /home/loic/src/ceph-qa-suite_firefly/suites/rgw/multifs/rgw_pool_type/erasure-coded.yaml /home/loic/src/ceph-qa-suite_firefly/suites/rgw/multifs/tasks/rgw_multipart_upload.yaml

which show the testing word as part of the job name. The https://github.com/ceph/teuthology/ page shows some more information about kernel choices but it's non trivial to figure out how to translate that into something that could be used in the context of teuthology-lock.

I'm not sure where to look and I would be grateful if you could give me a pointer to go in the right direction.

Cheers
